Whenever life gets you down, Mrs. Brown, and things seem hard or tough,

and people are stupid, obnoxious or daft, and you've had quite enough...

Just remember that you're standing on a that's evolving

And revolving at nine hundred miles an hour,

That's at nineteen miles a second, so it's reckoned,

A that is the source of all our power.

The and you and me, and all the that we can see,

Are moving at a million miles a day,

In an outer spiral arm, at forty thousand miles an hour,

Of the galaxy we call the .

Our itself contains 100 billion stars

It's 100,000 light years side to side,

It bulges in the middle, 16,000 light years thick

But out by us it's just 3,000 light years wide

We're 30,000 light years from galactic central point,

We go round every 200 million years

And our is only one of millons of billions

In this amazing and expanding Universe.

The Universe itself keeps expanding and expanding

In all the directions it can whizz

As fast as it can go, at the speed of light you know,

12 million miles a minute, and that's the fastest speed there is.

So remember when you're feeling very small and insecure

How amazingly unlikely is your ,

And pray there's intelligent life somewhere up in

Because there's bugger all down here on !
